}
}
but did not get response in recyclerview. what is the mistake?
Your data classes and JSON structure don't match.
Use JsonToKotlinClass plugin to create data class from json in Android Studio
Problem is with your data class "Users".. Check below data class for your reference:
data class Response(
#field:SerializedName("data")
val data: List<DataItem?>? = null,
#field:SerializedName("message")
val message: String? = null,
#field:SerializedName("status")
val status: Boolean? = null)
data class DataItem(
#field:SerializedName("country")
val country: String? = null,
#field:SerializedName("firstname")
val firstname: Any? = null,
#field:SerializedName("invitation_code")
val invitationCode: String? = null,
#field:SerializedName("flag")
val flag: String? = null,
#field:SerializedName("gender")
val gender: String? = null,
#field:SerializedName("city")
val city: String? = null,
#field:SerializedName("pmdc")
val pmdc: String? = null,
#field:SerializedName("bio")
val bio: Any? = null,
#field:SerializedName("created_at")
val createdAt: String? = null,
#field:SerializedName("switch_role")
val switchRole: String? = null,
#field:SerializedName("speciality")
val speciality: String? = null,
#field:SerializedName("password")
val password: String? = null,
#field:SerializedName("updated_at")
val updatedAt: String? = null,
#field:SerializedName("affiliation")
val affiliation: String? = null,
#field:SerializedName("license_owner")
val licenseOwner: String? = null,
#field:SerializedName("id")
val id: String? = null,
#field:SerializedName("state")
val state: String? = null,
#field:SerializedName("remember_token")
val rememberToken: String? = null,
#field:SerializedName("email")
val email: String? = null,
#field:SerializedName("image")
val image: String? = null,
#field:SerializedName("license_purchase_id")
val licensePurchaseId: String? = null,
#field:SerializedName("address")
val address: Any? = null,
#field:SerializedName("profile_active")
val profileActive: String? = null,
#field:SerializedName("degree")
val degree: String? = null,
#field:SerializedName("lastname")
val lastname: Any? = null,
#field:SerializedName("phone")
val phone: Any? = null,

val age: Any? = null,
#field:SerializedName("username")
val username: String? = null,
#field:SerializedName("status")
val status: String? = null
)
Your Users class does not match the structure of your json, so you won't be able to parse it. Looking at your json, it's more like:
data class ResponseMessage(
val message: String,
val status: Boolean,
val data: List<User>
)
data class User(
val id: Long,
val username: String,
...
)

I'm using Github's search API in Android App through retrofit
https://api.github.com/search/users?q=user
The API Service file states as :
interface ApiService {
#GET("search/users")
suspend fun getUsers(#Query ("q") searchQuery: String)
: UserResponse
}
Meanwhile, the data class is :
data class UserResponse(
val total_count: Int,

val received_events_url: String,
val repos_url: String,
val site_admin: Boolean,

}
But, I'm having an error

I want to use a Moshi adapter with a generic type.
Here is my generic type adapter code,
fun <T> getObjectFromJson(typeOfObject: Class<T>, jsonString: String): T? {
val moshi = Moshi.Builder().build()
val jsonAdapter: JsonAdapter<T> = moshi.adapter<T>(
typeOfObject::class.java
)
return jsonAdapter.fromJson(jsonString)!!
}
This code is not working. It is throwing an error,
Platform class java.lang.Class requires explicit JsonAdapter to be registered
But, If I don’t use a generic type like this,
fun getObjectFromJson(jsonString: String): UserProfile? {
val moshi = Moshi.Builder().build()
val jsonAdapter: JsonAdapter<UserProfile> = moshi.adapter<UserProfile>(
UserProfile::class.java
)
return jsonAdapter.fromJson(jsonString)!!
}
Then the code is working fine.
Here is the UserProfile class,
#Parcelize
#JsonClass(generateAdapter = true)
data class UserProfile(
#get:Json(name = "p_contact")
val pContact: String? = null,
#get:Json(name = "profile_pic")
var profilePic: String? = null,
#get:Json(name = "lname")
val lname: String? = null,
#get:Json(name = "token")
var token: String? = null,
#get:Json(name = "fname")
val fname: String? = null,
#SerializedName("_id")
#get:Json(name = "_id")
var id: String? = null,
#get:Json(name = "email")
var email: String? = null,
#SerializedName("refresh_token")
#get:Json(name = "refresh_token")
var refreshToken: String? = null
) : Parcelable
The typeOfObject is an instance of the Class<T> class already, you are calling ::class.java on it unnecessary: it returns Class<Class> and that's not what you want.
Just change
val jsonAdapter: JsonAdapter<T> = moshi.adapter<T>(typeOfObject::class.java)
to
val jsonAdapter: JsonAdapter<T> = moshi.adapter<T>(typeOfObject)
By the way: creating a new Moshi instance on each deserialization is suboptimal. You should reuse it.
I'm using a Moshi adapter to get the object from a JSON string. But, I'm getting an error,
java.lang.IllegalArgumentException: Platform class java.lang.Class requires explicit JsonAdapter to be registered
All the data members of the UserProfile class are only String type then why it is asking to create an explicit JsonAdapter?
MoshiDataConverter
class MoshiDataConverter() {
fun <T> getObjectFromJson(typeOfObject: Class<T>, jsonString: String): T? {
val moshi = Moshi.Builder().build()
val jsonAdapter: JsonAdapter<T> = moshi.adapter<T>(
typeOfObject::class.java
)
return jsonAdapter.fromJson(jsonString)!!
}
}
getObject method
fun <T> getObject(#Keys key: String?, typeOfObject: Class<T>?): T? {
val value = getString(key, null) ?: return null
return MoshiDataConverter().getObjectFromJson(typeOfObject!!, value)
}
UserProfile.kt
#Parcelize
#JsonClass(generateAdapter = true)
data class UserProfile(
#get:Json(name = "p_contact")
val pContact: String? = null,
#get:Json(name = "profile_pic")
var profilePic: String? = null,
#get:Json(name = "lname")
val lname: String? = null,
#get:Json(name = "token")
var token: String? = null,
#get:Json(name = "fname")
val fname: String? = null,
#SerializedName("_id")
#get:Json(name = "_id")
var id: String? = null,
#get:Json(name = "email")
var email: String? = null,
#SerializedName("refresh_token")
#get:Json(name = "refresh_token")
var refreshToken: String? = null
) : Parcelable
Your typeOfObject parameter is already a class reference, so you don't need to call ::class.java on it before passing it to the Moshi adapter.
Try replacing
val jsonAdapter: JsonAdapter<T> = moshi.adapter<T>(
typeOfObject::class.java
)
with
val jsonAdapter: JsonAdapter<T> = moshi.adapter<T>(typeOfObject)
So I'm trying to fetch an API with endpoint https://someURL.com/switching-product/switch?orderID=A001,
This is the returned JSON format as seen from Postman.
So I use this Interface in the NetworkConfig.kt class to fetch this endpoint:
//Endpoint: https://someURL.com/switching-product/switch?orderID=A001
interface getOutstandingOrderDetail{
#GET("switch")
fun getOutstandingOrderDetail(#Query("orderID") orderID: String): Call<OutstandingOrderDetailPOJODataClassData>
}
and store it in this data class (Generated by an Android Extension that generate POJO from JSON):
data class OutstandingOrderDetailPOJODataClass(
#field:SerializedName("data")
val data: OutstandingOrderDetailPOJODataClassData? = null,
#field:SerializedName("error")
val error: Error? = null
)
data class OutstandingOrderDetailPOJODataClassData(
#field:SerializedName("Header")
val header: OutstandingOrderDetailPOJODataClassHeader? = null,
#field:SerializedName("Detail")
val detail: List<OutstandingOrderDetailPOJODataClassDetailItem?>? = null
)
data class OutstandingOrderDetailPOJODataClassHeader(
#field:SerializedName("buyer_address")
val buyerAddress: String? = null,
#field:SerializedName("total_price")
val totalPrice: Int? = null,
#field:SerializedName("buyer_name")
val buyerName: String? = null,
#field:SerializedName("status_confirmed_yn")
val statusConfirmedYn: String? = null,
#field:SerializedName("order_date")
val orderDate: String? = null,
#field:SerializedName("outlet_id")
val outletId: String? = null,
#field:SerializedName("nip")
val nip: String? = null,
#field:SerializedName("jumlah_product")
val jumlahProduct: Int? = null,
#field:SerializedName("last_update")
val lastUpdate: String? = null,

#field:SerializedName("order_running_id")
val orderRunningId: Int? = null,
#field:SerializedName("status_tagged_yn")
val statusTaggedYn: String? = null,
#field:SerializedName("order_id")
val orderId: String? = null
)
data class OutstandingOrderDetailPOJODataClassError(
#field:SerializedName("msg")
val msg: String? = null,
#field:SerializedName("code")
val code: Int? = null,
#field:SerializedName("status")
val status: Boolean? = null
)
data class OutstandingOrderDetailPOJODataClassDetailItem(
#field:SerializedName("item_price_new")
val itemPriceNew: Int? = null,
#field:SerializedName("item_name_new")
val itemNameNew: String? = null,
#field:SerializedName("total_price")
val totalPrice: Int? = null,
#field:SerializedName("item_price")
val itemPrice: Int? = null,
#field:SerializedName("item_name")
val itemName: String? = null,
#field:SerializedName("status_refund")
val statusRefund: String? = null,
#field:SerializedName("detail_id")
val detailId: Int? = null,
#field:SerializedName("procode_new")
val procodeNew: String? = null,
#field:SerializedName("refund_date")
val refundDate: String? = null,
#field:SerializedName("request_refund")
val requestRefund: String? = null,
#field:SerializedName("procode")
val procode: String? = null,
#field:SerializedName("last_update")
val lastUpdate: String? = null,
#field:SerializedName("item_qty_new")
val itemQtyNew: Int? = null,
#field:SerializedName("order_id")
val orderId: String? = null,
#field:SerializedName("total_price_new")
val totalPriceNew: Int? = null,
#field:SerializedName("item_qty")
val itemQty: Int? = null,
#field:SerializedName("refund")
val refund: Int? = null
)
This is a code snippet of the fragment where I fetch the URL data:
private fun fetchOrderedItemListData() {
NetworkConfig()
.getOutstandingDetailOrderedItemListService()
.getOutstandingOrderDetailOrderedItemList("A001")
.enqueue(object :
Callback<OutstandingOrderDetailPOJODataClassData> {
override fun onFailure(
call: Call<OutstandingOrderDetailPOJODataClassData>,
t: Throwable
) {
Log.i("Order", "It Failed!!")
if (call.isCanceled) {
Toast.makeText(
(activity as AppCompatActivity),
"Request Aborted",
Toast.LENGTH_SHORT
).show()
} else {
Toast.makeText(
(activity as AppCompatActivity),
t.localizedMessage,
Toast.LENGTH_SHORT
).show()
}
}
override fun onResponse(
call: Call<OutstandingOrderDetailPOJODataClassData>,
response: Response<OutstandingOrderDetailPOJODataClassData>
) {
Log.i("Order", "Ordered Item FEtched -> \n ${response.body()}") <= This is for debugging purpose
binding.rvOrderedItemList.adapter =
response.body()
?.let { OrderedItemListAdapter(it, this#OrderDetailFragment) }
binding.rvOrderedItemList.layoutManager =
LinearLayoutManager((activity as AppCompatActivity))
}
})
}
As you can see above I use Log.i to try to print the response.body() in the LogCat, However it returns null in the Log Cat. You can see it here.
Am I missing something ? If there's any detail that I left out for this question, feel free to ask.
Your Retrofit function is set up as:
#GET("switch")
fun getOutstandingOrderDetail(#Query("orderID") orderID: String): Call<OutstandingOrderDetailPOJODataClassData>
The data type in the Call<> needs to match your JSON. You have data classes that match your JSON... but the root of that hierarchy is OutstandingOrderDetailPOJODataClass, not OutstandingOrderDetailPOJODataClassData. So, change your Retrofit function to:
#GET("switch")
fun getOutstandingOrderDetail(#Query("orderID") orderID: String): Call<OutstandingOrderDetailPOJODataClass>
I am facing problem while sending json object body using retrofit to the server. Below is the error.

Your UpdatePreviousDetails class has to have a constructor with no params to enable Gson (inside Retrofit) to convert your object into JSON.
EDIT
class UpdatePreviousDetails() {

var DateOfLeaving: Date? = null
